Overview of Thermalright Assassin X120 Refined SE CPU Air Cooler
The Thermalright Assassin X120 Refined SE CPU Air Cooler is priced at $17.90, making it an economical choice in the CPU cooler market. With its four heat pipes and a PWM fan, it is designed for efficient cooling while maintaining a low noise level. This cooler is compatible with a broad range of Intel and AMD sockets, including LGA 1150, 1151, 1155, 1200, 1700, and AM4/AM5. Its compact design, measuring 125mm x 71mm x 148mm, fits comfortably in most medium-sized computer cases.
Thermalright has been a reputable brand in the cooling market for over 20 years, focusing on innovative solutions for CPU cooling. The Assassin X120 utilizes AGHP technology, which helps to mitigate the effects of gravity on cooling performance, ensuring efficiency whether the cooler is mounted vertically or horizontally.
Overview of Vetroo V5 CPU Air Cooler
The Vetroo V5 CPU Air Cooler has a higher price point of $27.99, which is about 56% more expensive than the Thermalright Assassin X120. This cooler boasts five heat pipes and features addressable RGB lighting, appealing to users looking for both performance and aesthetics. It operates within a fan speed range of 800 to 1700 RPM, providing flexibility in cooling performance based on user requirements.
This cooler is also compatible with a variety of Intel and AMD sockets, including LGA 1851, 1700, 1200, 1150, and AM4/AM5. Its design focuses on achieving better thermal conductivity through high-density aluminum fins and a larger copper base, ensuring optimal cooling for high-performance CPUs.
Cooling Performance
When it comes to cooling performance, the Vetroo V5 has an edge due to its five heat pipes compared to the four in the Thermalright Assassin X120. The additional heat pipe in the Vetroo cooler allows for better thermal conductivity, which can be crucial for high-performance systems under load.
Both coolers utilize PWM technology, but the Vetroo V5 offers a wider fan speed range from 800 to 1700 RPM, allowing for dynamic adjustments based on thermal demands. This flexibility can lead to quieter operation during low-demand tasks while ramping up cooling performance when needed. The Thermalright model maintains a steady fan speed of 1550 RPM, which may not cater to as broad a range of cooling scenarios.
Noise Levels
The Thermalright Assassin X120 is designed to operate at a maximum noise level of 25.6 dB(A), which is relatively quiet and suitable for users who prioritize a silent computing experience. Its PWM fan is engineered for efficient cooling without generating excessive noise.
On the other hand, the Vetroo V5's design, featuring nine fan blades and vibration rubber pads, aims to deliver a silent operation while maximizing airflow. Though specific noise levels for the Vetroo V5 are not provided, its emphasis on low-noise operation suggests it is also designed with quiet computing in mind. However, the broader speed range may lead to variability in noise levels depending on the workload.
Aesthetic Appeal
A significant difference between the two coolers is their aesthetic design. The Vetroo V5 features addressable RGB lighting that can sync with the motherboard, allowing users to customize their builds visually. This aspect is particularly attractive to gamers and PC builders looking to enhance their system's appearance.
In contrast, the Thermalright Assassin X120 has a more understated design with no RGB lighting. This cooler’s focus is primarily on performance rather than aesthetics, making it a suitable choice for users who prefer a more classic look or those who want to keep their builds straightforward.
Installation and Compatibility
Both coolers are designed for easy installation and come with the necessary mounting hardware for compatibility with Intel and AMD sockets. The Thermalright Assassin X120 specifically mentions the inclusion of metal fasteners for both platforms, ensuring a secure fit regardless of the CPU used.
The Vetroo V5 is similarly compatible with multiple socket types and emphasizes ease of installation, though it does not specify the materials of its mounting hardware. For users who frequently upgrade or change components, ease of installation can be a significant factor in choosing a cooler.
Price Comparison
The Thermalright Assassin X120 is priced at $17.90, making it a budget-friendly option for those seeking effective cooling without breaking the bank. In contrast, the Vetroo V5 comes in at $27.99, which is about 56% higher than the Thermalright model. While the Vetroo offers additional features such as RGB lighting and an extra heat pipe, the price difference may not be justifiable for users primarily focused on performance.
For users with tighter budgets or those who do not require the advanced features of the Vetroo V5, the Thermalright Assassin X120 presents a compelling value. However, for those willing to invest more for aesthetics and slightly enhanced performance, the Vetroo V5 may be worth the higher cost.
Which should you buy?
Choosing between the Thermalright Assassin X120 Refined SE and the Vetroo V5 ultimately depends on your priorities. If you are looking for an affordable, efficient cooler that delivers solid performance with minimal noise, the Thermalright Assassin X120 is an excellent option. However, if you desire enhanced aesthetics with RGB lighting and slightly better thermal performance due to the additional heat pipe, the Vetroo V5 justifies its higher price. Consider your budget, performance needs, and aesthetic preferences to make the best choice for your build.
